Being a lower end card we've cut down on our usual array of benchmark runs slightly. There are no AA or AF tests and we have also removed Rydermark and Supreme Commander. Apart from that we have our normal layout which tests everything from synthetic to real world gaming, while also looking at power, sound and heat.

We have compared the 8400GS against the 8500GT, from a pricing perspective you're looking at around $20AUD / $15US extra for the 8500GT (about 20% more).
